- Rain-Dodging Headlights Can Now Handle Snow
Last year we reported that researchers from Carnegie Mellon University and Intel had developed a prototype headlight that could avoid lighting up raindrops, giving a driver a clearer view of the road ahead (see “Smart Headlights See Through Rain and Snow”). That team has now developed a version able to cope with wind-blown snowflakes, too, and tested it during a snowstorm in Pittsburgh.
